随着总共四个新兴星座（北斗、伽利略、准天顶卫星系统、印度区域导航卫星系统）以及全球定位系统（GPS）和格洛纳斯（GLONASS）的持续现代化，卫星导航领域目前正经历着巨大变化。面对这些挑战，国际全球导航卫星系统服务组织（IGS）发起了多全球导航卫星系统实验（MGEX），以便尽早熟悉新系统，并为将其纳入高精度全球导航卫星系统建模和分析做准备。本文报道了截至2013年9月新星座和MGEX项目的状况。描述了到目前为止建立的多全球导航卫星系统网络的离线和实时部分，并介绍了初始数据产品。重点介绍了各个系统的近期成果，并确定了迈向全面的多全球导航卫星系统服务所需的步骤。
With a total of four new and emerging constellations (BeiDou, Galileo, QZSS, IRN SS) as well as the ongoing modernization of GPS and GLONASS the world of satellite navigation presently experiences dramatic changes. Facing these challenges, the International GNSS Service (IGS) has initiated the Multi-GNSS Experiment (MGEX) to enable an early familiarization with the new systems and to prepare their incorporation into high-precision GNSS modeling and analysis. The paper reports on the status of the new constellations and the MGEX project as of September 2013. The offline and real-time segment of the multi-GNSS network built up so far are described and initial data products are presented. Recent results for individual systems are highlighted and necessary steps towards a comprehensive multi-GNSS service are identified.
